Excellent value, great view and will feel like home! It is a bit far from the sites, but in the end we enjoyed that with an authentic experience. The best food in Bangkok is down the street and you’ll get an authentic (but shockingly clean and lovely) experience. Best red curry is just down the road for a great price.
Oh, and great pool for doing laps.
FYI the subway is a good 12 - 15minute walk and you’ll use it a lot! We actually loved that in the end because of all of the great food.
Just a note - technically travelers are not allowed to stay in this building for under one month, though there dies not seem to be any issues- just a lot of signs.
